Welcome to Math in Focus®: Singapore Math by Marshall Cavendish, the world-class math curriculum from Singapore adapted for U.S. classrooms based on updated math standards.

The Math in Focus® program consists of Student textbooks and Workbooks that work together. At school, your child will use the Student textbook to learn math concepts and practice extensively to develop a deeper understanding. Your child will also participate in activities or games, and discuss his or her fi ndings in class.

Your child will be assigned pages from the Workbook to be completed as individual work. This will include:

Practice problems to reinforce math skills and concepts

Put on Your Thinking Cap!

• Challenging Practice problems to help broaden your child’s thinking skills and extend their understanding of concepts

• Problem Solving questions to challenge your child to use relevant problem-solving strategies for non-routine problems

Math in Focus® addresses topics in greater depth at each grade. This year, your fourth grader will focus on:

• building problem-solving skills and strategies

• multiplying and dividing with 1-digit and 2-digit numbers

• using tables, graphs, data, and probability

• adding and subtracting with fractions and decimals

• understanding relationships between fractions and decimals

• studying angles, line segments, area, and perimeter

ActivityLarge numbers can be intimidating, but when their place-value

structure is understood they are actually very simple.

Encourage your child to draw a place-value chart like the one

below. Place a few coins or other small household objects in each

column (any number from 0 to 9) and have your child write the

number that is formed. An example is shown.

NumberTen

ThousandsThousands Hundreds Tens Ones

43,012

• Ask your child to make statements about the numbers using

what he or she has learned about place value. For example,

the digit 3 in 43,012 stands for 3 thousands or 3,000.

• Have your child compare three numbers using the

vocabulary shown above.

Dear Family,In this chapter, your child will study numbers to 100,000.

Some of the skills your child will practice are:

• reading and writing large numbers in different ways

• comparing and ordering numbers

• finding the rule in a number pattern

Standard form: 73,816

Word form: Seventy-three

thousand, eight hundred sixteen

Expanded form: 70,000 + 3,000 + 800 + 10 + 6

28,539 31,707 32,807

31,707 is greater than 28,539.

31,707 is less than 32,807.

32,807 is the greatest number.

28,539 is the least number.

32,807 is 1,100 more than 31,707.

You can help your child build confi dence as well as communication skills in mathematics by practicing newly acquired skills at home. Throughout the year, I will be sending home letters that will help you understand what your child will be learning in school. These letters contain activities that give you and your child an opportunity to work together to hone new skills.

You can encourage your child’s efforts by taking advantage of opportunities to use math in everyday situations. Allow your child’s math class-work or homework to guide you in determining the appropriate level of challenge.

While reading newspapers and magazines, invite your child to:

• estimate sums and differences

• look for tables and line graphs and interpret them

• keep an eye out for decimal numbers

At home or at the supermarket, challenge your child to:

• identify symmetric shapes and tessellations

• calculate the change he or she will get after buying groceries

• estimate monthly household bills

On car or bus trips, allow your child to:

• read decimal distances on the odometer

• calculate a fraction of the total distance traveled between two places

• make associations between turns and right angles

I look forward to working with you and your child this year. Please contact me if you have any questions about the program or about your child’s progress.

School-to-Home Connections

Estimada familia,Bienvenidos a Math in Focus®: Singapore Math by Marshall Cavendish, el plan de estudios de matemáticas del cuarto grado de Singapur, adaptado para clases de EE.UU. según normas matemáticas actualizadas.

El programa Math in Focus® consta de textos y libros de trabajo para el estudiante que se utilizan en conjunto. En la escuela, su hijo utilizará el texto para el estudiante para aprender conceptos matemáticos y practicar extensamente con el objeto de lograr una mayor comprensión. Su hijo también participará en actividades o juegos, y conversará sobre sus hallazgos en clases. A su hijo se le asignarán páginas del libro de trabajo para que las complete como trabajo individual. Esto incluirá:

Problemas prácticos para reforzar las destrezas y los conceptos matemáticos

¡Pon tu cerebro a trabajar!

• Problemas prácticos desafi antes para ayudar a ampliar las destrezas de pensamiento y su comprensión de los conceptos

• Preguntas para resolución de problemas para desafi ar a su hijo a utilizar estrategias de resolución de problemas no rutinarios

Math in Focus® abarca temas con mayor profundidad en cada grado. Este año, su hijo de cuarto grado se centrará en:

• crear destrezas y estrategias de resolución de problemas

• multiplicar y dividir con números de uno y dos dígitos

• usar tablas, gráfi cos, datos y probabilidad

• sumar y restar con fracciones y decimales

• entender relaciones entre fracciones y decimales

• estudiar ángulos, segmentos, área y perímetro

Puede ayudar a su hijo a crear confi anza y destrezas de comunicación en matemáticas al practicar en casa las destrezas recientemente adquiridas. Durante el año, le enviaré cartas que le permitirán entender qué estará aprendiendo su hijo en la escuela. Estas cartas contienen actividades que brindan a usted y a su hijo una oportunidad para trabajar juntos con el fi n de perfeccionar sus nuevas destrezas.

Puede estimular los esfuerzos de su hijo al aprovechar las oportunidades de utilizar matemáticas en situaciones cotidianas. Permita que el trabajo en clase o las tareas de matemáticas de su hijo lo orienten para determinar el nivel adecuado de desafío.

ActividadLos números grandes pueden ser atemorizantes, pero una vez

que se entiende la estructura del valor posicional, en realidad son

muy simples. Estimule a su hijo para que dibuje una tabla de valor posicional

como la que aparece a continuación. Coloque algunas monedas

u otros objetos pequeños domésticos en cada columna (cualquier

número de 0 a 9) y pida a su hijo que escriba el número que se

formó. Se muestra un ejemplo.

NúmeroDecenas de

millarMillares Centenas Decenas Unidades

43,012

•Pidaasuhijoquehagaenunciadossobrelosnúmeros

usando lo que ha aprendido sobre el valor posicional. Por

ejemplo, el dígito 3 en 43,012 corresponde a 3 millares o

3,000.

•Pidaasuhijoquecomparetresnúmerosqueutilizanel

vocabulario que aparece más arriba.

Estimada familia:En este capítulo, su hijo estudiará los números hasta el 100,000.

Algunas de las habilidades que practicará su hijo son:

•leeryescribirnúmerosgrandesdediferentesformas

•compararyordenarnúmeros

•encontrarlareglaenunpatrónnumérico

Forma estándar: 73,816

28,539 es el número menor.

32,807 es 1,100 más que 31,707.

Vocabulario para practicarCapítulo 1 Trabajar con números enteros

Cuando lea periódicos y revistas, invite a su hijo a:

• estimar sumas y diferencias

• hallar tablas y gráfi cas lineales e interpretarlas

• estar atentos a los números decimales

En la casa o en el supermercado, inste a su hijo a:

• identifi car formas simétricas y teselaciones

• calcular el cambio que recibirá después de comprar abarrotes

• estimar las cuentas domésticas mensuales

Durante viajes en automóvil o autobús, permita que su hijo:

• lea distancias decimales en el odómetro

• calcule una fracción de la distancia total recorrida entre dos lugares

• haga asociaciones entre giros y ángulos rectos

Espero con interés trabajar con usted y su hijo este año. Comuníquese conmigo si tiene alguna pregunta sobre el programa o sobre el avance de su hijo.
